1. A method comprising:
removing a damaged portion of a substrate to form an exposed surface of the substrate, wherein the damaged portion removed from the substrate includes a case hardened material,
delivering, by a material delivery device, a filler material to the exposed surface of a substrate, wherein the substrate comprises a first ferrous material, wherein the filler material comprises a second ferrous material and a carbon-based material;
directing, by an energy delivery device, an energy toward a volume of the filler material to join at least some of the filler material to the exposed substrate to form a component, wherein the joined filler material replaces the case hardened material of the damaged portion of the substrate; and
heat treating the at least some filler material joined to the substrate to case-harden a layer, wherein heat treating the at least some filler material joined to the substrate to case-harden the layer includes directed laser hardening of the at least some filler material joined to the substrate with the energy delivery device to case-harden the layer.
